Idisable 'redefine thumbnail on save' in 'model info - file'.
Saving is instantly again in any display mode.

Well saving here took really like 5-10 minutes (on 2xSSD in RAID0) with a model of 10MB (but with lots of detail).

With your tip it's saving within a second. Great tip and you're my hero of the day. I'm not sure what 2014 does but it really seems a bug in SU 2013.

Thanks!!

That's the one I tried. But doesn't really a nice result.

I got a outside wall which needs some thickness. It's a bit of an odd shapen and I don't found a smart extrude tool which is smart enough to give it all thickness.

This is the shape:

I know it's a weird shape because not all angles are equal but curious what's the best way. The thickness has to go to the inner side of the model.

So you mean I modelled my rug in Sketchup for nothing... http://sketchup.fizion.nl/huis50.jpg color has to be changed and it still needs some finetuning
